Fluoride in human milk.

Reported contents of fluoride (F) in human milk vary considerably. The aim of this study was to determine the F content in human milk under different levels of F intake using a siliconfacilitated microdiffusion technique, which had a good accuracy and precision. The mean F concentration of colostrum from mothers in a 1.0 ppm and a 0.2 ppm F area was 0.36 +/- 0.02 mumol/l (+/- SEM) and 0.28 +/- 0.02 mumol/l, respectively. The mean F concentration of mature milk from a 1.0 ppm F area was 0.37 +/- 0.04 mumol/l. Within the 1.0 ppm F area, the intra- and interindividual differences in F concentration were very small. No statistically significant difference in milk F concentration between the two areas was found. Consequently, breastfed infants living in a 1 ppm or a 0.2 ppm F area will have an approximately equal F intake of 5-10 micrograms per day, in spite of great differences in F intake among the nursing mothers.

Long-term effect on mother-infant behaviour of extra contact during the first hour post partum. I. First observations at 36 hours.

The immediate post partum period may be particularly important for the developing relationship between mother and infant; little is as yet known, however, of the long-term effects of hospital practice during this period. This study examines the effect of extra contact during the first hour following delivery. An extra skin to skin contact and suckling contact was given to 22 primiparous mothers and their infants. One control group of 20 primiparous mothers and infants and a second one of 20 multiparous mothers and infants was given routine care immediately after birth. All mothers and infants were healthy with normal pregnancies and deliveries. At 36 hours a first observation was made of maternal and infant behaviour during breast feeding in all three groups. At this stage primiparae with extra contact showed behaviour much more like the behaviour of multiparae with routine care. Infants of primiparae with routine care cried most frequently. The behaviour of mothers of boys differed more from group to group than did that of mothers of girls.

Long-term effect on mother-infant behaviour of extra contact during the first hour post partum. II. A follow-up at three months.

Primiparous mothers and their infants who had an extra 15-20 minutes' suckling and skin to skin contact during the first hour after delivery, behaved differently at 36 hours post partum compared with a control group without this extra contact. The present study is a 3-month follow-up of these mothers and infants by means of direct observation of mother-infant free play and a personal interview with the mothers. Mothers in the extra contact group spent more time kissing and looking en face at their infants; these infants smiled more often and cried less frequently. A greater proportion of the mothers with extra contact were still breast feeding at 3 months. The influence of extra contact on behaviour was more pronounced in boy-mother than in girl-mother pairs.
